Adjusting NORM (standard curve) temperature compensation

Press button twice briefly to activate the

line editing mode.

The split-screen main window shows

which GESTRA bus devices can be

indicated:

■ High-level limiter NRS 1-41

■ Low-level limiter NRS 1-40

■ Level switch NRS 2-40

■ Level controller NRR 2-40

■ Conductivity controller LRR 1-40

Press button four times briefly.

The NORM (standard curve) temperature compen-

sation is suitable for steam boilers operating with

variable pressures, which means that the steam

boilers do not feature fixed working pressures/

temperatures (e. g. low load 10 bar, peak load 15 bar).

The standard curves of 11 feedwater conditioning

agents with different conductivities compensate the

thermal influences of the measurement within the

rated operating range. In our example we have started

from the factory set “TK:LIN” mode.
